SPECIFICATION forming part of Letters Patent No. 432,212, flat'l filly 15, 1890. Application filed November 2l, 1889. Serial No. 3311116. (No model.)

To aZZwtom it may concern;

Be it known that' I, CHRISTIAN NELSON, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements' in Cork-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the saine,

-ret'erencebei'nghadto theaccoinpanyingdrawings,l which form a part of this speciication.

My invention relates to an improved ma chine for making corks; and itl consists in a frame having mounted thereon in suitable guides two carriages adapted to move at right angles to each other, a means for holding the blank piece of cork and releasing the saine, and devices for moving the said'carriages toward or along the face of a grnding-wheel, together with certain other details ot' construction and combination of parts, as'will be fully set forth hereinafter. y

In the accompanying drawings, Figure l is a plan view of my improved machine. Fig. 2 is a sectional elevation of the same, partly shown in section.

To put my invention into practice I provide a frame a, of, suitable size and form of construction, having formed in the direct-ion of its length the female portion Z9 of a dovetail slide. Operating in this .slide Z) is a carriage c, provided with a similar slide CZ, arranged in an opposite direction to that below and provided with a second carriage e. Mounted on the top of this last-mentioned carriage ,8, in suitable bearings f g, are two short shafts 7L z', one of which is slightly bent to and secured in its bearing f by a set-screw j. This shaft h may be moved in the direction of its length and held in any desired position by the set-screwj. On the inner end of this shaft 7i is loosely attached a clutch Zt for engaging with one end of the cork Z. The other shaft 'Z is supported loosely in its bearings g, and is also provided with aclutch m for engaging with the cork Z.

tary movement by a suitable belt. About this saine shaft 'L' is a coil-spring o, secured against a pinp and one of the bearings g' in a maiiner that when the said shaft 'Z is moved to re- Rigidly attached to this shaft t -1s a pulley-Wheel n for giving the same a ro-4 lease the cork Z the saine will recover or go back to its original position. Secured to one end of the lower carriage c by a pivot q is a lever r, provided with an opeiislot s, which engages with an upwardly-promoting p in t, attached to the upper or top carriage e in a manner that the said carriage e and its several parts may be moved toward or away from the fiat face of alarge grinding-wheelu. Attached to one end of the lower carriage c are two rods fu, which nieve through two bearings springs tiiids a bearing, 4the other ends of these springs a; 1esting against the carriage c. -Attached to thi same carriage c is a cord or 'chain y, which passes over a small rollers and thenattached to a foot-treadle a'. lThis treadle a when operated inoves the carriages c e in the direction of the length of' the inacliine and are brought, back to their former position by the two ccilffsprings at:

In operation the `cork is cut in suitable lengths .and a single piece placed between the two clamps 7c m. By means of the lever fr the said piece Zis brought in contact with the'side of a large grinding-Wheel a, the shaft t is given a rotary motionLand the cork Z ground circular in form and then removed by drawing the said shaft i back. This shaft L may either be revolved by power or the saine turned by hand by means of a smallv hand.- wheel Z1', secured to the cuter end of the saine.

In order to make a tapering cork, the entire machine is canted or turned so that the carriages and the work clamped therein lie at an angle to the plane of the vertical workingsiirfaces on-the grinding-wheel instead of being parallel therewith, as shown in Fig. l, and the machine, together with its carriages and several appliances, is secured in the desired position by bolts c', passing through slots d', formed in the ends of the frame d. The grinding-wheel fa is provided on one of its faces with annularleand-paper rings e', as clearly shown in Fig. L, each of which being of a different grade or degree of fineness, so that when the blank is iirst moved against a coarse ring the edges may be quickly removed and then by means of the treadle the Said nu, against which the yone end of two coil` IOO cork moved along the face of the wheel'a to plaira, and desire to secure by Letters Patent, 1S-

In a machine for grinding oorlcs, the oombination of an endwise-znovable carriage c, a 5 rotary grinding-disk arranged alongside of said carriage c with its lateral working-face adjacent thereto, springs for normally impelling the carriage c in one direction and substantially parallel with the lateral workingfaee of said grinding-disk, atreadle connected to the carriage for moving. the samein a eontrary direction, another carriage e mounted on the carriage c to slide in aline at right angles to the movement of the carriage c, alever fnlcrurned at one end on the carriage c and 15 connected directly to the carriage e for mov# ing the latter carriage at will toward or from thegrinding-disk, and the rotary work-ol amps mounted `on the carriage e, as and for the purpose described.

In testimony that I claim the foregoing I hereunto affix my signature this 24th day of October, A. D. 1889.
